I don't use them so I was only going by what their Seller section shows on payments. If that is the case I would definitely open up a ticket with their support department. Seems bitcoins price goes up all of these shady pools and exchanges get even more greedy. Once you get your money off of them I would avoid using Nicehash in the future, as there are a lot more trustworthy pools to mine at and which don't gouge you with 3-4% fees.
